HYDRAULIC CYLINDER PROJECT REPORT
HYDRAULIC CYLINDER PROJECT REPORT report
Abstract— Before opening the jacks, first insert the notched end of the handle into the release valve, turn the operating handle clock wise until release valve is closed. Do not over tighten the valve. Insert operating handle into the socket and ram is steadily raised by the load is thus raised. The ram will stop rising when the required height is reached.Lower the ram by turning the release valve. Counter-clockwise with the notched end slaked it slowly when a load is applied or accidents would occur. Before operating, estimate the weight of the load. Do boot overload the jack beyond its rated load. Select point of action according to the gravitational centre place the jack on the hardness ground if necessary; place a hard plank under the jacks so as to avoid tottering or falling during operation. When more than one jack is used at the same time is important to operate the different jacks at a speed with equal load. Otherwise, there is danger of falling of the entire fixture. For best results use specially blended jack oil. If such oil is not readily obtainable, the equivalent international oil specification is SAE10.Violent shocks must be avoided during the operation. Do not overload, do not adjust the valve.Hydraulic systems often require directional control valves, pressure relief valves and pilot operated check valves when actuators or hydraulic motors are operated. Hydraulic system components such as Cetop and cartridge valves are used to form a hydraulic circuit. The advantage of these interchangeable ranges of valves is that they are common throughout the world and can be added to and replaced from most valve manufacturers. Hydraproducts offer the CETOP03/NG6 and CETOP05/NG10 sizes, as well as a range of suitable valve manifolds, single and multi-station.Solenoid Directional Control Valve, these have a four-landed control spool. Solenoid coils move the spool position in order to change the direction of hydraulic oil flow. Conformimg to CETOP standards they interchange with most manufacturers. Pressure Relief Valve, these modular valves are sandwiched underneath the solenoid valves. These hydraulic pressure relief valve will open to limit the pressure in the control line. Cartridge Vavle verisons and in-line verisons are also available in line-block format with BSP ports. Flow Control Valves, common in both in-line and modular versions they are adjusted in order to control the flow rate. The CETOP modular versions can be configured to control flow either way, via the use of a sandwiched seal plate. Pilot operated check valve, containing pressure in the service ports is a common requirement to prevent hydraulic cylinders from movement. This range of valves are all capable of flow rates of 60 litres/minute and are rated to a pressure of 320 bar.
